l3experimental – Ex­per­i­men­tal LaTeX3 con­cepts

The l3­ex­per­i­men­tal pack­ages are a col­lec­tion of ex­per­i­men­tal
im­ple­men­ta­tions for as­pects of the LaTeX3 ker­nel, deal­ing with
higher-level ideas such as the De­signer In­ter­face. Some of them
work as stand alone pack­ages, pro­vid­ing new func­tion­al­ity, and can
be used on top of LaTeX2ε with no changes to the ex­ist­ing ker­nel.

The present re­lease in­cludes:

l3­color, which pro­vides sup­port for set­ting col­ors
us­ing a range of color mod­els

l3­draw, a code-level in­ter­face for con­struct­ing draw­ings

l3str, sup­port for string ma­nip­u­la­tion;

xcoffins, which
al­lows the align­ment of boxes us­ing a se­ries of ‘han­dle’
po­si­tions, sup­ple­ment­ing the sim­ple TeX ref­er­ence point
